I mean... this question needs a more nuanced answer, because it affects all levels of the game.
Obviously, you want youths to learn how to respect others, not just elders, but others. Its a key part of growing up. Putting your hands in your hips and looking at someone is not something that should be deemed disrespectful, especially when you participate in sports. Flopping is highly disrespectful, yet I havent seen a ref throw a flag for a flop in a minute. In fact, refs actually reward flopping. If they shake hands before the game and shake hands after the game, that's the kind of respect people should have doing a sport.
When it comes to college football, I never liked the taunting and celebration rule. To me, its stupid. For a large part, these kids enjoy their last years of football playing a game that could potentially ruin their health at any significant moment at an extremely high rate. We tell kids to enjoy what they are doing and have fun, yet the moment they enter college, they cant dance in the endzone after scoring a TD? Give me a break. If you flip the ball and signal a first down, you get a flag. Come on now.
The fact that this trend has made its way into the NFL (a big thanks to the Mora family for that) is even worse. The average NFL career lasts three years. When you leave the league, your body will be full of scars from injuries suffered during your career and you will probably end up getting some more after your career because your joints are ****ed up. And people want to tell me they cant have fun celebrating a big play?
You need to be bat**** crazy to play this game. Like, your wires in your head need to be different material and they need to be put in different places. Its a ******* dangerous game and there is a ****load of emotion within the game that needs to get out somehow. Every play has a calculated risk that you might end up in a hospital with a really bad injury that could affect your life. Yet, when you do a big play, you are expected to just walk back to the huddle as if nothing happened.
I dont understand it. Let people have fun doing what they like doing. Theres enough times in life where we have to be like robots. Not during sports.
